The process of translating constructs into measurable variables can be difficult. During this process, various types of error can occur that distort relationships of interest. As a result, conclusions about a particular theory or model's usefulness can be inaccurate.

Confidence in the measurement of social networks & social support constructs can be increased if there is support for the validity and reliability of the measure when used in a population similar to the study population.

This section explores how some of the social networks & social support constructs have been measured, as well as strengths and limitations of existing measures.
